IMPROVEMENT IN STREET-LAMPS.

Specification forming part of Letters Patent No. 48,461, dated June 27, 1865.

4ing had to the accompanying drawings, making a part of this specification, in which- Figure l is a side sectional view of my invention; Figs. 2 and 3, detached face views oi' two rctlectors which are applied to the lamp.

Similar letters of reference indicate corresponding parts in the several ligures.

This invention relates to an' application ot' 'reflectors-to the lamp, as hereinafter shown andfdescribed, whereby the light which is now allowed to beradiatcd upward through the top ofthe lamp, and consequently lost, is reected downward upon the pavement.

To-enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

Arepresents a street-lamp, which may be constructed in the usual way, and therefore does not require a minute description.

B is a reflector, which may be of pyramidal form, and has an opening, ct, at its center, directly over the iiamc C. 'lhis reector may be constructed ot any proper material, and it is placed or secured in the lamp just above the flame (l, at the lower part of the top b of the lamp.

D is a reflector, which maybe also oli' a pyramidal form, and is placed in the bottom of the lamp, the gas-tube E, when gas is used, passing through the apex of the refiector, as shown in Fig. l.

The reflectors B D may have smooth o rugated surfaces, audit will be seen by ring to Fig. l that the rays of light iro iiame C will be reflected in the direction cated by the red lines, and the light quen tly thrown down upon the pavement. he lower reflector, D, is important, as it throws outward from the lamp the rays of light which are radiated downward frornhthe flame within the lamp, and which would otherwise be lost or not rendered available.

Having thus described 'my invention, what I claim as new, and desire to secure by Letters Patent, s-

The two reiiectors BD, with' vitreous corrugacd surfaces, in combination with the streetlainp A C E, all constructed, arranged, and operatin g as and for the purposes specified.
